In some countries this could be classed as child porn and get you into trouble with the authorities. Be careful.

Its a curling puck or whatever they call them. (curling is like bowing done on ice) The pucks are usually very hard and heavy and this looks to be one of them.

Their government cannot afford traffic lights. Curiously there used to be some huge squares in Paris that were a free-for-all just like that. Each square had its resident wrecker truck which did seem to be a bad omen. In such places all one can really do is to drive the front of the car so to s...

How will it be cooled and oiled? Who will be able to recondition it when it wears? Those banana shaped pistons look so complicated to make so what is the point? Nowadays 16 valve turbo four cylinder engines can easily produce 100HP per litre and I sorry to say that Kugel-Motor vs Hayabusa look...

See //igor.chudov.com/manuals/Redi-Line-Generators-Manual.pdf (add the hypertext bit) In my honest opinion these machines are superb. OK some people reckon they are current guzzlers but this is not so when the load is substantial (it would be stupid to use a 500W machine to run a shaver or to ...

@Billionair777 What dictionary are you using? Cockney Rhyming Slang, an American dictionary, a gangsters dictionary or what? "Pawky" allegedly means cunning or sly and its allegedly a Scottish word. I do however know exactly what the young lad said and it WAS NOT "pawky". I think you lost ...

A little tractor and a wire rope is much easier and the stump can be jerked out. DO NOT attach the rope higher than the rear axle. (if its higher than the axle the tractor can flip over) In the good old days before terrorism became commonplace one could allegedly get dynamite from the tin mines...

Crime FIGURES are down as nowadays a tremendous amount of stuff is not "crimed up". Recently I reported the theft of an aluminium road sign that warned of a T junction. It looked as if the thief had used a rock to hammer it upwards and off its pole. The police told me that I COULD NOT REPORT TH...

Well like it or not it was Hitler who moved the world from the horse-and-cart age to the modern age. It was also the German Rocketry Club that ended up putting man on the moon.

@ryan0929931 Aint you got any planks or shovels in America? I used to work at a place where our big cherry picker regularly got stuck in the mud. By putting at least a foot thickness of planks (battens is the proper term) under its jacks it could lift itself out of the holes. Sand and gravel ...

Top class special forces also have to be linguists as its not just about blasting-off several clips of ammo. In a hostage situation the difficult part is to only kill the bad guys (any fool can kill everybody). Take the London Embassy siege for example. In this case it would appear that not on...

There is a worse transmission than that! It is used on a famous brand of German car that used to cost £57,000 a couple of years ago. It is a six speed that can be driven in automatic or manual mode and it uses special lubricant. The lubricant is pumped through a pipe in the radiator in order to...

@punji73 An electric fan is more reliable than those viscous coupled heaps of junk. It is also more efficient for a fan to blow than to suck. A "solid" fan from an old Ford Granada is a better bet than spending £50 on a new viscous hub but you will need an electric fan as well. If you have a...

What if the old belt is one tooth or more out? My "new" 300TDi isn't right at all. All four injectors do add power but it runs lumpy with poor top speed. An interesting clue is a rather hot exhaust on idle also the engine barks almost like a 2 stroke.

If you want something really good buy a Lister CS as designed in the 1930s. It will still be running when the lesser makes have gone to the great scrapyard in the sky. For something more modern the "Startomatic" sets are very good. As to the Chinese "Silent" models a fairer test would be again...

The YSE (E for Early) and YSB (B for Between) don't use the Bosch patent injection system. The YSM (M for Modern) does and these will idle much more reliably. The early Yanmar models use a strange fuel relief needle which wears and the adjustment of this needle is rather difficult to get right....

They do make a small air cooled model as well but this engine is the Z482 (Z stands for "zwei"which is German for two) Several companies marinise these engines, Betamarine and Nanni Diesel are two. AFAIK The Farrymann Yellow River Star is the smallest marine diesel on the market (AKA Bukh DV7)

@eliasaarnio Old style alternators have the fan outside. The newer type such as the Bosch Compact Alternator have the fans (two of them) inside. This is a lot safer as the old external fans can cut like a buzz saw.

Why doesn't he put his name on the speedo? (LOL)

The concrete pipe method is very good and was used by workers building the M6 near Penrith in 1965. Just put a foot of sand in the bottom and sheet it over. Sheet over the pipe ends then install your sleeping bag. No lodgings to pay for and no expense of travelling to work. Some of those bloke...

@billwho62 They had thousands and thousands of slaves and they rolled the stone blocks on rollers up inclined planes. Even today there are some quarries where cunning methods are used to extract and move the stones. In the Middle Ages in Europe there were cranes worked by treadmills but in Egyp...

So sus?

There was a club in Worcester UK called The Roundhouse. It was supposed to have really hard bouncers. Unfortunately all the thugs for fifty miles or more would come to see if they could beat-up the bouncers because if they could they were "hard". It was really bad and a bloke I knew who worked...
